BAND-WHEEL FOB SAUSAGE-GRINDERS.

Specification of Letters Patent.

Patented July 8, 1919.

Application filed January 25, 1919. Serial No. 272,994.

To all whom it may concern:

Be it known that 1, ROBERT L. SWEETNAM, a citizen of the United States of America, residing at Armington, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Bandl/Vheels for Sausage-Grinders, of which the following is a specification.

My invention relates to band wheels for sausage grinders.

My invention has special reference to a correlating means, effecting attachment of standard band wheels to shaft members of different sizes.

The object of my invention is to provide a band wheel and correlating elements, adapting the band wheel for attachment to shafts of different sizes, and has special use in connection with sausage grinders,

My invention includes the forming of the shaft receiving opening in the hub of a band wheel, to accommodate its application to speciallyformed shafts of said sausage machines; to a tapered, expansible and resilient,

spacing or filler member adapted for association with the opening in the hub member, and with shaft members, whereby the band wheel may be applied to shafts of different size.

My invention includes details as toform and relationship of parts hereinafter more particularly pointed out.

Referring to the drawings- Figure 1 is a side elevation of a sausage grinder, showing a band wheel attached thereto;

Fig. 2 is a vertical sectional view showing my invention applied;

Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 2;

Fig. l is a detail View;

Fig. 5 is a plan of a metal blank used in forming a spacing or correlating member.

Sausage grinders are used very extensively by farmers. Indeed, they are to be found in almost every farmers home. Sausage grinders vary in size from very small machines, that are hand operated only, to very large machines that are power operated only, but intervening between these two extremes, are two classes of machines known on the market as Nos. 12 and 22 that are almost exclusively farmers machines, and are sold in very large numbers.

Both Nos, 12 and 22 are ordinarily hand operative, but the operation of either involves very considerable labor. With the advent of gasolene engines, the farmer is rapidly adapting all machinery to be operated from power, and a very limited amount of promotion with respect to my band wheel attaching means has demonstrated that it will meet with large demand.

My problem has not been so much the matter of finding a way to attach a band wheel, to different sized shafts, as to the point of finding a spacing element or intervening member for interposition between a band wheel and such shafts that would compensate for inequalities and variations that would result from wear on shafts, and from ordinary rough casting of band wheels.

The point is, that the band wheel and its associated means for attachment purposes must be very cheap in first cost.

Referring to the drawings, A indicates generally, a sausage grinder. The shafts of sausage machines Nos. 12 and 22 are of different diameters respectively, but I have illustrated only one of such shafts, and it is herein indicated as 10.

Shaft 10 in either No. 12 or 22 is tapered on uniform lines, and is segmentally cut to provide a locking face 11, as shown.

13 is a band wheel having the laterally extending hub member 14:. The hub member is provided with the tapered opening, as shown, following the lines of taper of the sausage grinder shafts hereinbefore referred to, having a segmental face corresponding in general inclination to the segmental face 11 of shaft 10.

20 is a filler or spacing member, adapted to be formed from blank 21 (Fig. 5), 'upon lines exactly conformatory to the lines respectively, both longitudinally and transversely, of shaft members as 11, and the opening-in the hub member 14 of the band wheel, and having its free ends spaced apart as shown in Fig. 4. p

The filler member is of spring metal, rendering it compressible or eXpansi-b-le to serve useful purposes hereinafter explained.

In applying my invention, it is my purpose to select a band wheel of simple, standard form, and apply it to shaft of either sausage machines N o. 12 or No. 22. In so applying it, filler member may be either inserted in the opening in the hub of the band wheel, or placed loosely upon the shaft. The band wheel being applied to the shaft, it will be forced to its proper relation for close fit, by means of threaded thumb nut 22, applied to shaft 10, which said shaft is normally provided with female opening, as 23, adapted to receive said screw.

The necessity for resiliency of filler member 20 and the provision, in connection therewith, for expansion or contraction, will appear, when it is suggested that sausage grinder shafts may have become worn by use of hand cranks thereon, or where in equalities may develop as a result of the use of rough cast band wheels. The filler member will compensate, either by expansion or compression, through force applied in connecting the band wheels to the shafts, whereby close-fit relation will, in all cases, be attained.

I am aware that it is common practice to provide fillers or proper spacing elements to accommodate variations between openings in members to be related to shafts, but such matters are wholly outside of the thought involved herein.

The purpose of my invention is to provide a simple, standard, band wheel for attachment to shafts of sausage grinders Nos. 12 and 22, as hereinbefore noted, to the end thatlarge numbers of such hand operative sausage grinders may be convertible into power driven machines.

WVhat I claimis:

1. In combination, interchangeably with shalfts of different sizes, and of defined form, including a tapered end, of a band wheel provided with an opening in its hub member conformatory to the taper of said shaft ends respectively, and a resilient spacing or filler member for interposition therebetween, formed on lines in agreement with the contour of the opening in said hub member, and also with that of the shaft members respectively, having its free ends spaced apart to permit compression or expansion thereof.

2. In combination, interchangeably with shafts of difi'erent sizes, and of different form, including a tapered end and a cut face, of a band wheel, a laterally oflset hub connected with said band wheel, there being an opening in said hub member conformatory to the shape and taper of said shaft ends respectively, and a resilient spacing or filler member for interposition therebetween, formed on lines in agreement with the contour of the opening in said hub member, and also with that of the shaft members, respectively. having its free ends spaced apart to permit compression and expansion thereof.

In testimony whereof I have affixed my signature.
